Capture dynamic images with a fast-aperture ultra wide-angle zoom lens

Covering focal lengths from 11-20mm (a full-frame equivalent of 16.5-30mm), this ultra wide-angle lens for APS-C mirrorless cameras features a maximum aperture of F2.8 and allows users to fully enjoy the distinctive depth-of-field and unique perspective provided by an ultra wide-angle lens. Enjoy a higher degree of photographic freedom than ever before, such as taking regular snapshots at the 20mm end, which has a rather natural angle of view, and then challenging yourself to take powerful ultra wide-angle shots at the wide end - all while enjoying the easy handling, creamy bokeh and other advantages that fast-aperture lenses offer. The lens shines in various scenarios, including architecture, landscape, indoor environmental portraits, travel and interior photography.

A design so compact and light weight, it's hard to believe it's an ultra wide-angle lens

The lens was designed to be exceptionally compact and lightweight, an ideal match with APS-C mirrorless cameras. It has an overall length of 86.2mm (3.4 in)[3], and weighs only 335g (11.8 oz). Imagine a lens so small and light that it is hard to believe it's a full-fledged fast-aperture ultra wide-angle zoom. You can concentrate on shooting without worrying about bulk or weight. When used with a compatible APS-C mirrorless camera body, you'll enjoy carefree handheld shooting of still images and find it comfortable to shoot video even when using a compact tripod or gimbal.

Enjoy the outstanding optical performance of the TAMRON 11-20mm F2.8

The 11-20mm F2.8 is a high-resolution lens that focuses on superb image quality as a full-fledged fast-aperture ultra wide-angle zoom. The optical construction includes 12 elements in 10 groups. High resolution performance is maintained across the entire frame with the well-balanced arrangement of two GM (Glass Molded Aspherical) lens elements. Two LD (Low Dispersion) and one XLD (eXtra Low Dispersion) lens elements are used to suppress the chromatic aberrations that tend to occur when shooting at the wide-open aperture of fast-aperture lenses. These features combine to render clear, crisp images. In addition, the use of the lens correction features built into Sony cameras lets users harness extra lens performance gains.

Indulge in the exciting world of wide-angle macro with an MOD of 0.15m

The MOD (Minimum Object Distance) is just 0.15m (5.9 in) at the widest end. This extreme close-range shooting performance allows you to get as close to a subject as you like. The maximum magnification ratio is 1:4 (an astonishing feat for an ultra wide-angle lens) and it unlocks powerful wide-angle macro shooting utilizing the unique perspective that makes near objects look larger, and distant objects smaller. Additionally, using the F2.8 maximum aperture produces a shallower depth-of-field that creates soft bokeh in the background, allowing users to take distinctive images with unique expressions.

High performance autofocus system means you'll own every shooting opportunity

The AF drive on the 11-20mm F2.8 includes an RXD motor unit to help you stay focused on the action. RXD uses an actuator to precisely control the rotational angle of the motor, allowing it to directly drive the focusing lens without passing through a reduction gear. A sensor that precisely detects the position of the lens enables high-speed and accurate AF, which is ideal when shooting continually moving subjects or recording video. And with a focusing system that is both smooth and quiet, the 11-20mm F2.8 lets you shoot free from stress not worrying the drive sound in a quiet environment.
